Cummins Emission Solutions EcoFit Single Module Aftertreatment System

Cummins Emission Solutions, a subsidiary of Cummins Inc., is introducing the first of its next generation of ultra-high efficiency aftertreatment systems, the EcoFit Single Module.

• Up to 60% smaller and 40% lighter compared to the EPA 2013 solution
• Improves emissions reduction performance
• Smaller size enables better heat management and retention for improved fuel economy capability
• Simple single-pass exhaust flow design delivers low back pressure
• Simpler, innovative packaging allows for fewer variations, offering system integration benefits, while providing a more robust and reliable system
• Meets GHG and fuel efficiency standards for EPA 2017
• Specifically addresses the needs of medium- and heavy-duty engine customers in low emissions markets
• Advancements in catalyst technologies have allowed the DPF to have a bigger ash capacity, permitting for increased time between maintenance events and minimal operator intervention
• Improvements in NOx reduction capabilities in the SCR system have been enabled by the use of the EcoFit UL2 Liquid-Only Urea Dosing System
• Features simpler chassis integration as the UL2 system does not require engine coolant lines to and from DEF injector
• Provides more efficient atomization of urea and minimized urea deposits, thus requiring fewer regeneration events while experiencing optimal use of DEF
